Description:
Details :
+Severity : major
+Bugzilla : 14634
+Description: socklnd prtocol version 3
+Details : With current protocol V2, connections on router can be
+ blocked and can't receive any incoming messages when there is no
+ more router buffer, so ZC-ACK can't be handled (LNet message
+ can't be finalized) and will cause deadlock on router.
+ Protocol V3 has a dedicated connection for emergency messages
+ like ZC-ACK to router, messages on this dedicated connection
+ don't need any credit so will never be blocked. Also, V3 can send
+ keepalive ping in specified period for router healthy checking.

+Severity : major
+Bugzilla : 15983
+Description: workaround for OOM from o2iblnd
+Details : OFED needs allocate big chunk of memory for QP while creating
+ connection for o2iblnd, OOM can happen if no such a contiguous
+ memory chunk.
+ QP size is decided by concurrent_sends and max_fragments of
+ o2iblnd, now we permit user to specify smaller value for
+ concurrent_sends of o2iblnd(i.e: concurrent_sends=7), which
+ will decrease memory block size required by creating QP.
